I've commented out the NoDDC and LinearAlloc
and I still get nothing on the screen.

Can you comment on this (WW) which is describing the problem I see
(II) intel(0): Output configuration:
(II) intel(0): Pipe A is on
(II) intel(0): Display plane A is now enabled and connected to pipe A.
(WW) intel(0): Hardware claims plane A is off while software believes it is on
(II) intel(0): Pipe B is off
(II) intel(0): Display plane B is now disabled and connected to pipe B.
(II) intel(0): Output VGA is connected to pipe none
Why isn't the VGA output connected?
